Margaret Auten Hubbard, El Paso, Texas

I am seeking information on Margaret Auten Hubbard.The only solid, verifiable fact available to me is that she was signatory to her husband's death certificate in January, 1946 in El Paso, Texas.Her husband was Charles Banifield Hubbard (born 9 Aug 1887 in Erath County, TX).Charles died 3 Jan 1946 in ElPaso and was buried in the Masonic section ofEl Paso's Concordia Cemetery.Charles and Margaret probably married between 1924-1930.

I hope this rings a bell with someone.I am trying to get over, under or around my brick wall relative to Charles and Margaret.
